Merge branch 'ab/do-not-limit-stash-help-to-push'

"git stash" by default triggers its "push" action, but its implementation also made "git stash -h" to show short help only for "git stash push", which has been corrected. * ab/do-not-limit-stash-help-to-push: stash: don't show "git stash push" usage on bad "git stash" usage
